Internal combustion engine with charge air cooling through the air conditioning system

The invention relates to an internal combustion engine (10) for a motor vehicle with an air compressor (20), with the combustion air for the internal combustion engine (10) is compressed, and a charge air cooler for cooling the compressed combustion air. According to the invention the charge air cooler is formed by a heat exchanger of an air conditioning system, is also used for air conditioning of the vehicle interior of the motor vehicle. In this case the heat exchanger has a heat transfer matrix (30) having at least two separate areas (31; 32), and by the air compressor (20) compressed combustion air is supplied to a first region (31) of the heat transfer matrix (30), while air for air conditioning of the vehicle interior is fed to a second region (32) of the heat transfer matrix (30)
